Semiconductor devices having at least one barrier layer are disclosed. In some embodiments, a semiconductor device includes an active layer and one or more barrier layers disposed on either one side or both sides of the active layer. The active layer may be composed of a first compound semiconductor material, and the one or more barrier layers may be composed of a second compound semiconductor material. In some embodiments, the composition of the one or more barrier layers may be adjusted to increase an optical dipole matrix element.
